1. rectangle wxyz is dilated by a scale factor of 3.
which is an algebraic representation of the dilation?
a. (x,y) → (6x, y)
b. (x,y) → (3x, 3y)
c. (x,y) → (2x,y)
d. (x,y)—+(x, y)

B

Step-by-step explanation:

If the numbers are unknown but there is a scale factor of 3, you'll have to multiply x and y by 3.

y=250x+2000

Step-by-step explanation:

The farmer starts with 2000 trees and adds 250 each year.

Year 0   2000

Year 1   2000 + 250 = 2000+ 1(250)

Year 2   2000 + 250 +250 = 2000 + 2(250)

Year 3   2000 + 250 + 250 + 250 = 2000 + 3(250)

Year 4   2000 + 250 + 250 + 250 + 250 = 2000 + 4 (250)

Year X   2000 + 250x
